God's Prophet (a.s) said: “I swear by the Lord who has control over my life that you shall not enter Heaven unless you believe. You will not believe unless you love each other. Do you want me to tell you what to do to help you love each other? Establish saying “Salam” (peace, greetings, hello) as the official way to greet each other.”
وقال (صلى الله عليه وآله): والذي نفسي بيده، لا تدخلوا الجنة حتى تؤمنوا، ولا تؤمنوا حتى تحابوا، أولا أدلكم على شئ إذا فعلتموه تحاببتم؟ افشوا السلام.
